EDITS ON 4.0-4.3

Addresses an ADL identified technical edit request to bring consistency to the use of sections such as Rationale, Description, Requirements and Details. 

In so doing, several items previous in "Details" were moved into "Requirements." Addiitonally, to keep with somewhat consistent formatting of the previous set of requirements, formatting was changed and unintended meanings may have changed in some cases, so PLEASE CHECK BEFORE MERGING
